Means 'cute' in Japanese. Horrendously overused by fangirls on anything chibi. ANYTHING. Because they feel the need to repeat the three Japanese words they know OVER AND OVER. And they LEARNED said Japanese words by watching 'Naruto' in Japanese on YouTube ALL THE TIME.

YES, kawaii can be used for all these things - But Guys, PLEASE don't say it for cool and nifty and for family members and all that!! Only little girls can say everything's cute!! You'll get wierd looks!
